Pep Guardiola spent four seasons as manager of Barcelona and Thomas Muller believes his familiarity with the club will give Bayern Munich an edge.

"We know that Barcelona are one of the best teams in the world," he told his club's official website. "They have knocked out two huge teams in the Champions League. 

"But I am optimistic. I'm confident in the team - we want to win there.

"We know their potential. They have a great squad and covering [Lionel] Messi as a defender is not comfortable. 

"But we are preparing well. The coach knows Barcelona better than anyone. 

"He will give us the recipe in our hands; the rest we need to do as players."
